A video game is now being sold at 22% off for a price of $23.40. What was the original price of the video game?

Its $28.548

Step-by-step explanation:

Because 10 percent of 23.4 is 2.34 and times that by two is 4.68, but then you have to find that 2 percent so I found the 1 of percent of it which is .234. So since you want 2 percent multiply .234 by two so then just add 4.68 and youll get the answer .

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
